The most obvious difference between a low power and a high power microscope is that a high power microscope can resolve smaller features, which is usually achieved with objective lenses of greater magnification.
So, while examining the brine shrimp using the low-power lens and the high-power lens you will see more clear and magnified image in high power lens. High power lens gives you the minor details of brine shrimp.
By examining brine shrimp in High power lens I can tell which brine shrimp is more mature and what are the differences between them.
